问题描述

援助与这个例子<一个href=\"http://stackoverflow.com/questions/14848590/return-back-to-mainactivity-from-another-activity\">Return回到MainActivity从另一个活动
我复制codeS如下，

aid with this example at Return back to MainActivity from another activity I copy that codes as follow,

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
 <uses-sdk
    android:minSdkVersion="10"
    android:targetSdkVersion="15" />

<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
    android:name=".MainActivity"
    android:label="@string/title_activity_main" >
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />

        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>
<activity
    android:name=".Activity1"
    android:label="@string/title_activity_main" >
    <intent-filter>
        <action android:name="android.intent.action.ACTIVITY001" />

        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</activity>
<activity
    android:name=".Activity2"
    android:label="@string/title_activity_main" >
    <intent-filter>
        <action android:name="android.intent.action.ACTIVITY002" />

        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</activity>
<activity
    android:name=".Activity3"
    android:label="@string/title_activity_main" >
    <intent-filter>
        <action android:name="android.intent.action.ACTIVITY003" />

        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</activity>
</application>

因此​​，许多语句：操作机器人：名字=android.intent.action.MAIN;如果我会用自己的类路径来代替他们，他们也可以做的工作。什么是由这两种方式有什么不同？

So many statements: action android:name="android.intent.action.MAIN"; if I would use their class path to instead of them, they can also do the job. what's different from these two ways?

推荐答案

其错

    <action android:name="ACTIVITYNAME FOR INTENT" />


    <category android:name=""/> // android.intent.action.DEFAULT or android.intent.action.MAIN

android.intent.action.MAIN 是考虑到活动至极会先推出以及

android.intent.action.MAIN is given to the activity wich is going to launch at first and

android.intent.action.OTHER 来的活动得到休息的其他活动名为

android.intent.action.OTHER to the rest of the activities getting called by other activities

您的应用程序将参照清单，以获取活动首次发射，就吃主它

Your application will refer to the manifest to fetch the activity for first launch , havin MAIN in it
